A double barrier resonant tunneling diode (RTD) is formed and integrated with a level of CMOS / BJT / SiGe devices and circuits through processes such as metal-to-metal thermocompressional bonding, anodic bonding, eutectic bonding, plasma bonding, silicon-to-silicon bonding, silicon dioxide bonding, silicon nitride bonding and polymer bonding or plasma bonding. The electrical connections are made using conducting interconnects aligned during the bonding process. The resulting circuitry has a three-dimensional architecture. The tunneling barrier layers of the RTD are formed of high-K dielectric materials such as SiO2, Si3N4, Al2O3, Y2O3, Ta2O5, TiO2, HfO2, Pr2O3, ZrO2, or their alloys and laminates, having higher band-gaps than the material forming the quantum well, which includes Si, Ge or SiGe. The inherently fast operational speed of the RTD, combined with the 3-D integrated architecture that reduces interconnect delays, will produce ultra-fast circuits with low noise characteristics.

The invention provides a durable, lubricious coating for a medical article that can be prepared from a first polymer that is synthetic, soluble in a polar liquid, and having first reactive groups, and a second polymer that is synthetic, hydrophilic, and that includes second reactive groups. The first reactive groups and a portion of the second reactive groups react to bond the first polymer to the second polymer. A portion of the second reactive groups remains unbonded which, upon neutralization, provide lubricious properties to the coating. In some aspects the coating is formed using a crosslinking agent having latent reactive groups. The coatings provide particularly long dry out times and are very useful for catheterization processes. In addition, the coatings can be subject to sterilization with ethylene oxide and retain very good durable and lubricious properties.
